On the first street, the fraction of nonworking lights is 2/3.
On the second street, the fraction of nonworking lights is 1/6.
To find the total fraction of nonworking lights, we need to add these two fractions.
2/3 + 1/6 = (4/6) + (1/6) = 5/6
Therefore, the total fraction of nonworking lights on these two streets is 5/6. Answer: \boxed{\frac{5}{6}}.
